My notes say the ASA developer was the same as Adox Borax MQ, however there may have been a slight variation due to weight conversions. (numbers getting rounded up or down.

When the ASA film speed system was being set up there were a few US film manufacturers and all would have had some input. Agfa Asco was by then under Government control, there was also Dupont (who later took over Adox). Presumably there were others.
